Lycoriella ( Hemineurina ) brevicubitalis (Lengersdorf) — Frey (1942): 36; Menzel & Mohrig (2000): 408. Redescription . Female. Head . Dark brown. Eye bridge united, 2–3 facets wide. Maxillary palpus long, with 3 segments, all segments narrow, 1 st segment with 4 sharp setae, with a dorsal unbordered patch of sensilla. Scapus and pedicellus dark bown and roundish; antennal flagellomers missing in the specimen studied. Thorax . Postpronotum non-setose. Scutellum with 8 long and strong setae. Legs . Strong, with long tibial spurs; tibial spurs of mid and hind tibiae unequally long [one spur is about 1/4 shorter than the other]; tarsal claws without teeth. Wing . Large, anal lobe strong, hind veins distinct, stCuA short, 1/3 of bM; bM = r-m, bM non-setose, r-m with 4–5 setae distally, c/w 0.50. Body length 2,7 mm, wing length 2,5 mm. BIN . Unknown. Discussion . The species was described from females from Northern Norway by Lengersdorf (1926): for the lectotype designation and literature, see Menzel & Mohrig (2000). After a study of the lectotype, which so far is the only specimen of the species (in ZFMK) available for study, Menzel & Mohrig (2000) stated that the scutellum has many long and strong setae, the 1 st palpal segment has a unbordered patch of sensilla, the fore tibia has spine-like setae, and that R 1 /R complex is long (R 1 ends near the level of the base of the M-fork). We have studied the lectotype again and have found characters that might be helpful in identification of the male of this species and for supporting its placement in the genus Trichocoelina . Of the characters given above, only the somewhat unequally long spurs of the mid and hind tibiae as well as the high number of long scutellars are unusual for Trichocoelina . : Published as part of Vilkamaa, Pekka & Menzel, Frank, 2019, Re-classification of Lycoriella Frey sensu lato (Diptera, Sciaridae), with description of Trichocoelina gen. n. and twenty new species, pp. 1-67 in Zootaxa 4665 (1) on page 19, DOI: 10.11646/zootaxa.4665.1.1, http://zenodo.org/record/4000553 : {"references": ["Lengersdorf, F.
